Hello,

On:
	ftp.ci.com.au:pub/clayton
the files
	psim*
and	clayton-gdb*
and	binutils-*

can be used to build a very preliminary (alpha?) version a PowerPC simulator
module for GDB.  Interestingly, on a 386DX/33, it manages ~0.03mips.
The file psim.README describes things further.

		might be useful, Andrew :-)

(Thanks to Corinthian Engineering for making their ftp site available)
